The Thompson family is buying a car that can travel 70 miles on two gallons of gas. Assume that the distance traveled in miles y varies directly with the amount of gas used x. This can be represented by y = 35x. Graph the equation on the coordinate plane. How many miles does the car get per gallon of gas? (Exampie 2)

4. The weight of an object on Mars varies directly with its weight on Earth. An
object that weighs 50 pounds on Mars weighs 150 pounds on Earth. If an
object weighs 120 pounds on Earth, write and solve a direct variation equation
to find how much an object would weigh on Mars. (Example 4)
Determine whether each linear function is a direct variation. If so, state the
onstant of yariation. If not, explain why not.
